SPECIFICATION forming part of Letters Patent No. 396,007, dated January 8, 1889.

Application filed April 4, 1887. Serial No. 233,681. (No model.)

To all whom it may concern:

Be it known that I, DANIEL C. STOVER, a resident of Freeport, in the county of Stephenson and State of Illinois, have invented certain new an d useful Improvements in Tire Fabrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention is fully illustrated in the accompanying drawings, wherein- Figure l shows one corner of aplane fabric embodying my devices. Figs. 2, 3, 4, and 5 exhibit, upon a larger scale, various parts and details, which are hereinafter described.

In all the drawings, A A are wire coils interlocked and forming the body of the fabric, and B is a border-coil interlocking with one edge of said body. The ends E E of the coils A A interlock in pairs, and are inclosed by a border-coil, (l, which, like the coil B, is equal in vertical diameter to t-he thickness of the body of the fabric. IVithin the coil B is placed a smaller coil, G,which is closely wound, so that successive turns are in contact, and the whole forms a practically continuous iiexible bar. As indicated in Fig. 2, which is a section on the line y, the diameter of the coil G, added tothe diameter of the main coilwire, equals, approximately, the horizontal inner diameter of the coil B; hence when all are in place, as shown, there is little or no latf eral movement of the parts with reference to each other. \Vithin the coil C is placed a nearly-rigid bar, I, whose horizontal diameter is enough less than the corresponding inner diameter of the coil to permit it to occupy the space within the coil in common with the ends E E of the main coils. This bar is preferably, but not necessarily, equal in vertical diameter to the inner vertical diameter of the coil, as in Fig. Vhen thus equal, vertical compression of the coil is impossible. The length of the bar I is equal to the entire length of the fabric or piece to be provided with a border, and its end lis perforated, as at J, Fig. 4, in the axial line of the coil G. Through this perforation a nail, F, is driven into the end of the coil G, where, if it be slightly larger than the normal space within the coil, it is held more securely than if driven into the hardest wood.

A corner only of the fabric or mat is shown, its opposite sides or edges being precisely similar. It has, then, two opposite edges provided with the border-coil C and rod I, and two opposite edges each provided with the open coil B and close coil G. A series of practically in compressi ble bars, D, nearly equal in vertical thickness to the inner vertical diameter of the coils A, and at a short distance from each other, pass from coil G to coil G through the body and between the surfaces of the mat. Their concave ends, Fig. A2, lit the coils G G and maintain the distance between them, while the coils A and the inter-locked inclos4 ing-coil l prevent increase of'this distance.

In forming the fabric with .its borders, as described, one edge is completed with its coil. G in position. The bars I) are pushed into place from the opposite edge, each passing, as shown, Figs. l and 2, over the wire of one coil A and under the wire of the next. The otherl coil G is then inserted in its coil B, and the nails F are driven as described, firmly uniting the parts at each corner. The various members are now practically inseparable, and each maintains the others in position. By this construction I have a fabric or mat slightly liexible in directions transverse to two of its sides and highly flexible in directions transverse to its other two sides, and which maintains its general form, liatness, and thickness under the roughest usage.

The coils A are shown in the drawings as having plane upper and lower surfaces, and this form is of importance in this construction, as it affords along and perfect bearing upon the bars D. The border-coils are shown as cylindrical and the bars I D as solid and of nearly rectangular cross-section; but these forms are of no importance. I have also used screw-nails and screws in place of the nails F, and have used a third coil within the coil G in cases where the outer coil was quite large; but these are believed to be such obvious modifications as require no illustration.

I have shown and described the entire construction of a fabric or mat; but many of the IOO ventinn or am embodied in my prim'pzilonl's. giniil coil and the bai' may he rigidly 00nhnch l'onl'm's I d0 not` ('laim. nected :1t the corner of the fabric.
